Running Backs (5)
David Montgomery
Jahmyr Gibbs
Craig Reynolds
Benny Snell
Jason Cabinda (FB)
The Lions seemed to reveal who will be the No. 3 running back on Saturday, as Reynolds played every offensive snap in the first half and got 12 touches. His eight carries weren't especially fruitful, due to lackluster (to put it mildly) blocking up front (just 13 yards), but it was a little better in the passing game (four catche for 29 yards, on six targets).
The question here is how many more running backs the Lions keep, and who they are. Cabinda's role is more intangible than noticeable on the field, but he has value. Campbell has said special teams will be important to this position battle, and Snell was a core special teamer for the Steelers the last couple seasons.
Wide Receivers (6)
Amon-Ra St. Brown
Marvin Jones
Kalif Raymond
Josh Reynolds
Chase Cota
Dylan Drummond
(Jameson Williams-suspended)
Weighed against other positions, there's a battle for either one or two spots here. Cota had another good performance against the Jaguars, with a touchdown among his two receptions and a nice 28-yard punt return. He is becoming a roster lock.
Drummond's star has faded some with Cota's emergence, and he did have a rough drop on Saturday. But on the idea a sixth wide receiver is kept on the 53, he gets the nod.
Tight Ends (3)
Sam LaPorta
James Mitchell
Brock Wright
It's possible the Lions keep four tight ends, with Darrell Daniels as No. 4 and strictly a blocker. But the three standing locks here remain.
Offensive Line (9)
Penei Sewell
Taylor Decker
Frank Ragnow
Graham Glasgow
Jonah Jackson
Halapoulivaati Vaitai
Colby Sorsdal
Germaine Ifedi
Bobby Hart
As is the case for every team in the league, offensive line depth is a huge concern for the Lions. The options to add someone are of course not robust at this point, but if anyone is added they will have an opportunity to crack the last could spots here. Sorsdal is a lock.
